1 Exynos MIPI-DSIM Controller 2 ========================= 3 4 Required properties: 5 SOC specific: 6 compatible: should be "samsung,exynos-mipi-dsi" 7 reg: Base address of MIPI-DSIM IP. 8 9 Board specific: 10 samsung,dsim-config-e-interface: interface to be used (RGB interface 11 for main display or CPU interface for main or sub display). 12 samsung,dsim-config-e-virtual-ch: virtual channel number that main 13 or sub display uses. 14 samsung,dsim-config-e-pixel-format: pixel stream format for main 15 or sub display. 16 samsung,dsim-config-e-burst-mode: selects Burst mode in Video mode. 17 in Non-burst mode, RGB data area is filled with RGB data and 18 NULL packets, according to input bandwidth of RGB interface. 19 samsung,dsim-config-e-no-data-lane: data lane count used by Master. 20 samsung,dsim-config-e-byte-clk: select byte clock source. 21 It must be DSIM_PLL_OUT_DIV8. 22 DSIM_EXT_CLK_DIV8 and DSIM_EXT_CLK_BYPASSS are not supported. 23 samsung,dsim-config-hfp: HFP disable mode. 24 If set, DSI master ignores HFP area in VIDEO mode. 25 In command mode, this variable is ignored. 26 samsung,dsim-config-p: P value for PMS setting. 27 samsung,dsim-config-m: M value for PMS setting. 28 samsung,dsim-config-s: S value for PMS setting. 29 samsung,dsim-config-pll-stable-time: the PLL Timer for stability 30 of the ganerated clock. 31 samsung,dsim-config-esc-clk: escape clock frequency for getting 32 the escape clock prescaler value. 33 samsung,dsim-config-stop-holding-cnt: the interval value between 34 transmitting read packet (or write "set_tear_on" command) 35 and BTA request. After transmitting read packet or write 36 "set_tear_on" command, BTA requests to D-PHY automatically. 37 This counter value specifies the interval between them. 38 samsung,dsim-config-bta-timeout: the timer for BTA. This register 39 specifies time out from BTA request to change the direction 40 with respect to Tx escape clock. 41 samsung,dsim-config-rx-timeout: the timer for LP Rx mode timeout. 42 this register specifies time out on how long RxValid deasserts, 43 after RxLpdt asserts with respect to Tx escape clock. 44 - RxValid specifies Rx data valid indicator. 45 - RxLpdt specifies an indicator that D-PHY is under RxLpdt mode 46 - RxValid and RxLpdt specifies signal from D-PHY. 47 samsung,dsim-device-name: name of the device. 48 samsung,dsim-device-id: unique device id. 49 samsung,dsim-device-bus_id: bus id for identifing connected bus 50 and this bus id should be same as id of mipi_dsim_device. 51 52 Optional properties: 53 samsung,dsim-device-reverse-panel: reverse panel. 54 55 Example: 56 mipidsi@11c80000 { 57 compatible = "samsung,exynos-mipi-dsi"; 58 reg = <0x11c80000 0x5c>; 59 60 samsung,dsim-config-e-interface = <1>; 61 samsung,dsim-config-e-virtual-ch = <0>; 62 samsung,dsim-config-e-pixel-format = <7>; 63 samsung,dsim-config-e-burst-mode = <1>; 64 samsung,dsim-config-e-no-data-lane = <3>; 65 samsung,dsim-config-e-byte-clk = <0>; 66 samsung,dsim-config-hfp = <1>; 67 68 samsung,dsim-config-p = <3>; 69 samsung,dsim-config-m = <120>; 70 samsung,dsim-config-s = <1>; 71 72 samsung,dsim-config-pll-stable-time = <500>; 73 samsung,dsim-config-esc-clk = <20000000>; 74 samsung,dsim-config-stop-holding-cnt = <0x7ff>; 75 samsung,dsim-config-bta-timeout = <0xff>; 76 samsung,dsim-config-rx-timeout = <0xffff>; 77 78 samsung,dsim-device-id = <0xffffffff>; 79 samsung,dsim-device-bus-id = <0>; 80 81 samsung,dsim-device-reverse-panel = <1>; 82 }; 83
